Description

Technical Field

[0001] This invention belongs to the field of cultivation technology, specifically a cultivation auxiliary device based on agricultural technology. Background Technology

[0002] Crops are all kinds of plants cultivated in agriculture, including two main categories: food crops and cash crops (oil crops, vegetable crops, flowers, grasses, and trees). The growth of crops is inseparable from scientific and technological production techniques, as well as the machinery and equipment manufactured by new industries that can assist agricultural production.

[0003] Currently, commonly used vertical soilless cultivation allows crops grown vertically to receive ample sunlight, fully utilizes greenhouse space, increases yield per unit area, and improves economic efficiency. However, in practical applications, most vertical cultivation racks are dismantled and reinstalled. This dismantling process requires not only removing the racks but also dismantling the original water supply lines, inevitably leading to the death of some strawberry seedlings and causing economic losses. Furthermore, the varying distances and angles between plants at different positions on the racks and the light source can affect the sunlight exposure of some plants, hindering their growth and reducing crop yield. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, facilitate the disassembly and adjustment of the cultivation area without affecting plant growth, and ensure sufficient light exposure for the plants, this invention proposes a cultivation auxiliary device based on agricultural technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a cultivation auxiliary device based on agricultural technology, including a base plate, a fixing rod installed on the lower surface of the base plate, a column installed on the upper surface of the base plate, a bracket installed on the column, and a cultivation box installed on the bracket. An mounting cylinder is installed on the base plate. The column is assembled from multiple identical parts. The column is inserted into the mounting cylinder. A pressure cap is installed on the upper end of the column. A water guide pipe is installed in the middle of the column, and a water outlet pipe is installed on the cover. The two ends of the water guide pipe are connected to the water inlet pipe and the water outlet pipe, respectively. The cultivation box is equipped with a limiting tube, and the installation cylinder is equipped with a water receiving tray. The limiting tube drains excess liquid in the cultivation box into the water receiving tray, and the water receiving tray is equipped with a return water pipe. The return water pipe is connected to a circulation pump, which is started intermittently to pump water. A telescopic rod is installed on the base plate. The telescopic rod is elastic, and its upper end is fixedly connected to the bottom surface of the water receiving tray. The water receiving tray is slidably mounted on the mounting cylinder, which is rotatably mounted on the base plate. An inclined groove is provided on the side wall of the mounting cylinder, and a protrusion is installed on the water receiving tray. The protrusion and the inclined groove are matched with each other.

[0006] Preferably, the components of the column are magnetically attracted to each other, and the water pipe is attracted by the magnetism of the column.

[0007] Preferably, the limiting tube overlaps the edge of the cultivation box, and the center line of the outlet at the lower end of the limiting tube passes through the cultivation box. The portion of the limiting tube that rests on the edge of the cultivation box has a flat rectangular cross-section.

[0008] Preferably, the portion of the limiting tube located inside the cultivation box is provided with a telescopic structure.

[0009] Preferably, the cultivation box is equipped with a cover plate, the cover plate has a drainage hole, the cover plate is equipped with a pair of elastic strips, the elastic strips are equipped with threads, and the two ends of the threads are respectively connected to the two pairs of elastic strips.

[0010] Preferably, a slip ring is slidably mounted on the elastic strip, the slip ring is elastic, and the thread is connected to the slip ring.

[0011] Preferably, a guide groove is formed on the surface of the fixing rod, the upper end of the guide groove is deeper than the lower end, and a reinforcing rod is inserted into the guide groove.

[0012] The beneficial effects of this invention are as follows: 1. The cultivation auxiliary device based on agricultural technology described in this invention, by setting up an installation cylinder, a column, a pressure cover and a cultivation box, allows workers to remove the parts that make up the column one by one when adjusting or disassembling the cultivation area, which facilitates the removal and adjustment of the auxiliary device. At the same time, the nutrient solution stored in the cultivation box ensures that the plants will not be separated from the nutrient solution for a long time when adjusting the cultivation area, thus ensuring the normal growth of the plants. 2. The cultivation auxiliary device based on agricultural technology described in this invention, by setting a water receiving tray, telescopic rod and inclined groove, enables the auxiliary device to rotate back and forth on its own during use, so that the plants planted on the column can receive sufficient light, and avoid insufficient light for the plants on the column that are away from the light source, which would affect the growth of the plants. 3. The cultivation auxiliary device based on agricultural technology described in this invention, by setting a cover plate, elastic strip, slip ring and silk thread, fully fixes the plants planted on the cultivation box to prevent the plants from tilting or falling over. At the same time, by adjusting the relative position of the slip ring on the elastic strip, the plants are blocked by the silk thread during planting, thereby adjusting the depth of the plants in the cultivation box or preventing seedlings from falling into the cultivation box and affecting the growth of the plants.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] like Figures 1 to 10As shown, the cultivation auxiliary device based on agricultural technology of the present invention includes a base plate 1, a fixing rod 11 installed on the lower surface of the base plate 1 and inserted into the ground, a column 2 installed on the upper surface of the base plate 1, a bracket 3 installed on the column 2, a fixing hole 24 opened from top to bottom on the column 2, the bracket 3 installed in the fixing hole 24 by interference fit, a cultivation box 4 installed on the bracket 3, and a plant planted in the cultivation box 4; An mounting cylinder 21 is installed on the base plate 1. The column 2 is assembled from multiple identical parts. The column 2 is inserted into the mounting cylinder 21. A pressure cap 22 is installed on the upper end of the column 2. A water guide pipe 23 is installed in the middle of the column 2, and a water outlet pipe 221 is installed on the cover 22. The two ends of the water guide pipe 23 are connected to the water inlet pipe 211 and the water outlet pipe 221 respectively. The outlet of the water outlet pipe 221 is located directly above the cultivation box 4. The cultivation box 4 is equipped with a limiting tube 41, and the installation cylinder 21 is equipped with a water receiving tray 5. The limiting tube 41 discharges excess liquid in the cultivation box 4 into the water receiving tray 5, and the water receiving tray 5 is equipped with a return water pipe 52. When disassembling or readjusting the cultivation area, the staff first shuts off the circulating pump used for circulating nutrient solution and disconnects the circulating pump from the inlet pipe 211 and the return pipe 52. Then, the staff removes the cap 22 at the top of the column 2, takes the column 2 out of the mounting cylinder 21, and then pulls the base plate 1 and the fixing rod 11 out of the ground to move the installation position of the auxiliary device, thereby facilitating the adjustment of the cultivation area or the removal of the auxiliary device. Meanwhile, since the support column 2 is made up of multiple identical parts assembled together, when the staff disassembles and moves the support column 2, the staff can take out the components of the support column 2 out of the installation cylinder 21 in multiple steps, so as to avoid the support column 2, cultivation box 4 and the plants in the cultivation box 4 being too heavy and inconvenient for the staff to move. Meanwhile, since the plants are planted in cultivation box 4, when the auxiliary device is disassembled or its position is readjusted, a portion of nutrient solution will be retained inside cultivation box 4. This prevents the plants in cultivation box 4 from being separated from the nutrient solution for a long time when the auxiliary device is disassembled or its position is readjusted, which could easily cause the roots of the plants to dry out and become dehydrated, leading to the death of the plants.

[0016] In one embodiment of the present invention, there is mutual attraction between the components of the column 2, and the water pipe 23 is attracted by the magnetism on the column 2. When reinstalling the auxiliary device after repositioning, the workers first insert the fixing rod 11 into the ground to fully fix the base plate 1. Then, the workers install the parts that form the column 2 into the installation cylinder 21 one by one to form a complete column 2. During this process, after the parts that form the column 2 are inserted into the installation cylinder 21, they will adhere tightly to the water pipe 23 under the action of magnetism, making the parts that form the column 2 relatively stable. This makes it easier for the workers to install the remaining parts of the column 2 into the installation cylinder 21. At the same time, through the magnetic attraction between the parts that form the column 2 and the water pipe 23, and between the components of the column 2, each component of the column 2 can be stably installed inside the installation cylinder 21 before the column 2 is completely assembled. This prevents the components of the column 2 from tilting or falling over, which would affect the reassembly of the auxiliary device. In addition, the installation of the column 2 does not require much attention or support from the workers, which can reduce the workload and intensity of the workers.

[0017] In one embodiment of the present invention, the limiting tube 41 overlaps the edge of the cultivation box 4, and the limiting tube 41 The centerline of the lower outlet passes through cultivation box 4; The portion of the limiting tube 41 that rests on the edge of the cultivation box 4 has a flat rectangular cross-section. During use, the external circulation pump can transport the nutrient solution stored in the cultivation area to the auxiliary device and re-pump and store the excess nutrient solution, reducing the waste of nutrient solution and ensuring good plant growth through the flow of nutrient solution. At the same time, after the nutrient solution is transported to the inlet pipe 211 by the circulation pump, the nutrient solution will enter the guide pipe 23 and then be discharged downward through the outlet pipe 221 connected to the guide pipe 23. Since the outlet of the outlet pipe 221 is located directly above the cultivation box 4 and the cultivation boxes 4 are evenly distributed from top to bottom on the column 2, the nutrient solution overflows from the uppermost cultivation box 4 and falls into the lower cultivation box 4 after filling the uppermost cultivation box 4. Finally, it overflows from the lowermost cultivation box 4 and falls into the water receiving tray 5. It is then re-pumped by the circulation pump through the return pipe 52 connected to the water receiving tray 5, so that the nutrient solution is circulated again. During this process, as the nutrient solution in the cultivation box 4 gradually increases to the point of overflowing, the nutrient solution also gradually fills the limiting tube 41 through the limiting tube 41 installed on the cultivation box 4. Since the cross-section of the limiting tube 41 overlapping the edge of the cultivation box 4 is a flat rectangle, the nutrient solution in the cultivation box 4 passes over the overlap of the limiting tube 41 on the cultivation box 4 before overflowing. Then, according to the siphon principle, the excess nutrient solution in the cultivation box 4 is drawn out and discharged into the cultivation box 4 below, thus preventing the nutrient solution from overflowing from the outer wall of the cultivation box 4 and causing waste. Simultaneously, utilizing the siphon principle, the nutrient solution is drawn out through the limiting tube 41... Excess nutrient solution in cultivation box 4 can be drained quickly. Simultaneously, the process of the nutrient solution entering and exiting cultivation box 4 through limiting tube 41 fully agitates the solution, allowing oxygen to dissolve and preventing insufficient dissolved oxygen from affecting the normal growth of the plant's roots. Furthermore, the changes in the nutrient solution level in cultivation box 4 ensure that all plant roots are immersed in the solution, increasing the amount of root tissue immersed and facilitating nutrient absorption, thus promoting plant growth.

[0018] In one embodiment of the present invention, the portion of the limiting tube 41 located inside the cultivation box 4 is provided with a telescopic structure. When cultivating different plants, the auxiliary device addresses the varying nutrient solution requirements of each plant. By adjusting the telescopic structure on the limiting tube 41, the length of the limiting tube 41 within the cultivation box 4 changes. This allows for adjustments to the nutrient solution level left in the cultivation box 4 when excess nutrient solution is drained, such as completely submerging the plant's roots or partially submerging them. This adapts to the different growth needs of various plant species, ensuring their normal growth.

[0019] In one embodiment of the present invention, a cover plate 42 is installed on the cultivation box 4, and a drainage hole 421 is provided on the cover plate 42. The liquid discharged by the water outlet pipe 221 and the limiting pipe 41 enters the cultivation box 4 through the drainage hole 421. A pair of elastic strips 422 are installed on the cover plate 42, and a thread 424 is installed on the side of the elastic strip 422 facing the inside of the cultivation box 4. The two ends of the thread 424 are respectively connected to the two pairs of elastic strips 422. The cover plate 42 provides some protection for the cultivation box 4, preventing external debris from falling into it and contaminating the nutrient solution, as well as preventing debris from clogging the limiting tube 41 and hindering the drainage of excess nutrient solution. This would cause the nutrient solution to overflow and slip from the outer wall of the cultivation box 4, resulting in waste. Simultaneously, the elastic strips 422 on the cover plate 42 can fix the plants planted in the cultivation box 4, ensuring their relatively stable position and preventing or reducing the possibility of plants tilting, falling over, or falling off, thus ensuring normal plant growth. Furthermore, the threads 424 connected to the corresponding elastic strips 422 at both ends can block and hold the planted plants in place, preventing them from slipping during planting. After the growth bar 422 is squeezed and deformed, the seedlings fall directly into the cultivation box 4, affecting their growth or causing them to die. At the same time, different types of plants require different spaces for growth. Since the cultivation box 4 has a cover plate 42 installed at its opening and the cultivation box 4 is relatively long, the staff can directly adjust the relative position of the plants on the cover plate 42 and the number of plants planted on the cover plate 42. This avoids the situation where planting smaller plants results in a large distance between them, wasting planting space, or planting larger plants results in a small distance between them, causing them to block each other and resulting in insufficient light and affecting their normal growth.

[0020] In one embodiment of the present invention, a slip ring 423 is slidably mounted on the elastic strip 422, the slip ring 423 is elastic, and the thread 424 is connected to the slip ring 423; Because the slip ring 423 is elastic, after the staff changes the relative position of the slip ring 423 on the elastic strip 422, the slip ring 423 is pressed tightly against the elastic strip 422 under its own elasticity, thus fixing the position of the slip ring 423 on the elastic strip 422. Subsequently, as the relative position of the slip ring 423 on the elastic strip 422 changes, the elastic strip 422 deforms and the distance between the strips changes and is restricted when planting the plants. Thus, according to the growth needs of different plants and the size of the plants when planting, the depth of the plant in the cultivation box 4 is changed to ensure the normal growth of the plants and to prevent the plants from being planted too deep, which would affect their normal growth.

[0021] In one embodiment of the present invention, a telescopic rod 51 is installed on the base plate 1, and the upper end of the telescopic rod 51 is fixedly connected to the bottom surface of the water receiving tray 5. The water receiving tray 5 is slidably mounted on the mounting cylinder 21, the mounting cylinder 21 is rotatably mounted on the base plate 1, the side wall of the mounting cylinder 21 is provided with a slanted groove 212, the water receiving tray 5 is provided with a protrusion 53, the protrusion 53 and the slanted groove 212 are matched with each other, and the circulation pump connected to the return water pipe 52 is intermittently started to pump water. Because the circulating pump starts intermittently to transport and pump back the nutrient solution, the auxiliary device will gradually increase the amount of nutrient solution in the water receiving tray 5 during use. Then, under the gravity of the water receiving tray 5 and the nutrient solution, the water receiving tray 5 will gradually descend along the mounting cylinder 21. At the same time, since the mounting cylinder 21 is rotatably mounted on the base plate 1, and the side wall of the mounting cylinder 21 has a groove 212, and the protrusion 53 on the water receiving tray 5 cooperates with the groove 212, the descent of the water receiving tray 5 will drive the mounting cylinder 21 and the column 2 to rotate. This will allow the plants in the cultivation boxes 4 at different positions on the column 2 to change positions so that the plants can receive sufficient light and ensure normal growth. After the circulating pump starts and pumps out the nutrient solution in the water receiving tray 5, the water receiving tray 5 will return to the upper end of the mounting cylinder 21 under the elastic action of the telescopic rod 51. During this process, the column 2 will rotate back to its original position.

[0022] In one embodiment of the present invention, a guide groove 111 is provided on the surface of the fixing rod 11, the depth of the upper end of the guide groove 111 is greater than the depth of the lower end, and a reinforcing rod 112 is inserted into the guide groove 111. After the fixing rod 11 is inserted into the ground, the worker inserts the reinforcing rod 112 along the guide groove 111 on the fixing rod 11. At the same time, because the guide groove 111 is shallower at the end away from the base plate 1, the direction of the reinforcing rod 112 changes, causing the lower end of the reinforcing rod 112 to move away from the fixing rod 11 and insert into the soil. This improves the bonding force between the fixing rod 11 and the ground, ensuring that the base plate 1 is fully fixed to the ground and preventing the fixing between the base plate 1 and the ground from failing, which could cause the auxiliary device to tip over and cause a safety accident.

[0023] The specific workflow is as follows: When disassembling or readjusting the cultivation area, the staff first shuts off the circulating pump used for circulating nutrient solution and disconnects the circulating pump from the inlet pipe 211 and the return pipe 52. Then, the staff removes the cap 22 at the top of the column 2, takes the column 2 out of the installation cylinder 21, and then pulls the base plate 1 and the fixing rod 11 out of the ground. Meanwhile, since the column 2 is assembled from multiple identical parts, when the staff disassembles and moves the column 2, the staff can take out the components of the column 2 one by one from the installation cylinder 21 in multiple steps. Meanwhile, since the plants are planted in cultivation box 4, some nutrient solution will be retained inside cultivation box 4 when the auxiliary device is disassembled or repositioned. When reinstalling the auxiliary device after adjusting its position, the workers first insert the fixing rod 11 into the ground to fully fix the base plate 1. Then, the workers install the parts that form the column 2 into the installation cylinder 21 one by one to form a complete column 2. During this process, after the parts that form the column 2 are inserted into the installation cylinder 21, they will stick tightly to the water pipe 23 under the action of magnetic force, so that the parts that form the column 2 remain relatively stable. After the nutrient solution is delivered to the inlet pipe 211 by the circulation pump, it enters the guide pipe 23 and then is discharged downward through the outlet pipe 221 connected to the guide pipe 23. Since the outlet of the outlet pipe 221 is located directly above the cultivation box 4 and the cultivation boxes 4 are evenly distributed from top to bottom on the column 2, the nutrient solution overflows from the uppermost cultivation box 4 and falls into the lower cultivation box 4 after filling the uppermost cultivation box 4. Finally, it overflows from the lowermost cultivation box 4 and falls into the water receiving tray 5. It is then re-drawn by the circulation pump through the return pipe 52 connected to the water receiving tray 5, so that the nutrient solution is circulated again. During this process, as the nutrient solution in the cultivation box 4 gradually increases to overflow, the nutrient solution will also gradually fill the limiting tube 41 through the limiting tube 41 installed on the cultivation box 4. Since the cross-section of the part of the limiting tube 41 that overlaps the edge of the cultivation box 4 is a flat rectangle, the nutrient solution in the cultivation box 4 passes over the overlap of the limiting tube 41 on the cultivation box 4 before overflowing. Then, according to the siphon principle, the excess nutrient solution in the cultivation box 4 is extracted and discharged into the cultivation box 4 below. By adjusting the telescopic structure on the limiting tube 41, the staff changed the length of the limiting tube 41 inside the cultivation box 4. As a result, when excess nutrient solution was drained from the cultivation box 4, the liquid level of the nutrient solution left in the cultivation box 4 changed. The cover plate 42 provides some protection for the cultivation box 4, preventing external debris from falling into the cultivation box 4 and contaminating the nutrient solution, and preventing external debris from clogging the limiting tube 41. Simultaneously, the elastic strips 422 on the cover plate 42 can fix the plants planted in the cultivation box 4. Furthermore, the threads 424 connected to the corresponding elastic strips 422 at both ends obstruct and position the planted plants. When planting and cultivating different types of plants, different plants require different amounts of space for growth. Because the cover plate 42 is installed at the opening of the cultivation box 4 and the length of the cultivation box 4... The size is relatively large, and staff can directly adjust the relative position of the plants on the cover plate 42 and the number of plants planted on the cover plate 42. Because the slip ring 423 is elastic, after the staff changes the relative position of the slip ring 423 on the elastic strip 422, the slip ring 423 is pressed tightly against the elastic strip 422 under its own elasticity, thus fixing the position of the slip ring 423 on the elastic strip 422. Afterwards, as the relative position of the slip ring 423 on the elastic strip 422 changes, the elastic strip 422 deforms and the distance between the two strips changes and is restricted when planting the plants. Thus, the depth of the plant in the cultivation box 4 is changed according to the growth needs of different plants and the size of the plant when planting. Because the circulating pump starts intermittently to transport and pump back the nutrient solution, the auxiliary device will gradually increase the amount of nutrient solution in the water tray 5 during use. Then, under the gravity of the water tray 5 and the nutrient solution, the water tray 5 will gradually descend along the mounting cylinder 21. At the same time, since the mounting cylinder 21 is rotatably mounted on the base plate 1 and has a groove 212 on its side wall, and the protrusion 53 on the water tray 5 cooperates with the groove 212, the water tray 5 will drive the mounting cylinder 21 and the column 2 to rotate when it descends. This will allow the plants in the cultivation boxes 4 at different positions on the column 2 to change their positions so that the plants can receive sufficient light. After the circulating pump starts and pumps out the nutrient solution in the water tray 5, the water tray 5 will return to the top of the mounting cylinder 21 under the elastic action of the telescopic rod 51. During this process, the column 2 will rotate back to its original position. After the fixing rod 11 is inserted into the ground, the worker inserts the reinforcing rod 112 along the guide groove 111 on the fixing rod 11. Simultaneously, because the guide groove 111 has a shallower depth at the end furthest from the base plate 1, the inserted reinforcing rod 112 moves forward more easily. The direction changes, causing the lower end of the reinforcing rod 112 to move away from the fixed rod 11 and the reinforcing rod 112 to be inserted into the soil, thereby increasing the bonding force between the fixed rod 11 and the ground.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
